Worm feeding mechanics?

Im trying to understand how to feed my worms. I have searched google and and Oh Crap, How do earthworms work (just a math contest) thread. However i cant seem to find the basic feeding mechanics for them. IE where to put food, how many worms per conainer... If someone has a link to the original thread about this i would appreciate it. The Oh crap, etc thread takes up all the searches on this forum. 
Thanks,
